On my garden empty tea bags rotted down much, much later rather than sooner.
Fed up with seeing them scattered around the borders, I now throw them in
the
wheelie bin.

You can rip each bag in half as you chuck it in the compost bucket to
spread them out, of course, and the fibres in the bag itself will break
